Many manufacturers of excellent instrument plugins, such as Ivory Grand Pianos and Vienna Symphonic Library, have not yet converted to 64 bit audio, which, as Steve H has ably demonstrated in his videos, is a fantastic advance in Logic 9, allowing the use of a hugely increased amount of RAM, with all its advantages.
However, vsl have released Vienna Ensemble, and, for some extra money, Vienna Ensemble Pro (VEP). This, if I understand it correctly, allows the simultaneous use of 32 bit and 64 bit applications. Am I perhaps also right in saying that it enables vsl to operate in 64 bit mode ? My vagueness here stems from a general ignorance of things technical, but also from my perusal of a vsl web-site and set of tutorials, which I find very difficult to follow, even though they have improved them a good deal recently. They do respond with commendable speed to any question emailed to them, always very helpfully,but it seems unfair to bombard them too often with so many basic questions!
I love the Vienna Symphonic Library (vsl) - it's just amazing, even in the Special Edition and Special Edition Plus, which is the level I use - but though they have improved their web site and documentation recently, there is still a desperate need (which has been voiced by vsl users for some time) for a really good set of tutorials of the sort that I have seen from you, Rounik, for example.
So I would welcome any snippets of information and advice which you, or others, feel like giving. I'm sure many other aspiring composers would be similarly interested.
I suppose my basic question is given in the heading to this submission. "Why would I need VE or VEP ?"
